' being provided so that the fabric may subsequently be caused to adhere to another fabric, and it relates more particularly to the means for applying the adhesive preparation on to thesurface of canvas, ducks, puddings or the like used for stiffening and retaining the shape of garments of various kinds. It has been proposed to smear the entire surface of canvas, ducks and paddings and like fabric with an adhesive,

preparation but it is found in practice that fabric so treated and afterward caused to adhere to another fabric'makes the whole too stiff and unyielding so that the comfort, appearance and shape of a arment made with this class of material is far from being satisfactory and the older and more expensive method of securing the stiffening fabric in position by sewing is still generally used.

Undcr my invention I apply the adhesive preparation to the surface of a fabric so that it lies thereon in ridges which may be either continuous from one end of the fabric to the other and arranged in straight lines parallel to each other, or diverging or if desired, the lines of ridges of-adhesive substance may be curved or arranged in any suitable and desired combination of curves and (or) straight or. crooked lines or the ridges may be in short lengths with a break between and arranged in any desired combination of line and (or) curve as hereinbefore described. Under my invention I may also apply the adhesive substance to the surface of a fabric in spots instead of the ridges as hereinbefore described and in this case the spots would also be arranged in any desired combination of line and (or) curve. The adhesive substance is applied to fabric in the manner hereinbefore described by passing the fabric between two rollers arranged one above the other, the

bottom roller being partly immersed in a tank or receptacle containing the adhesive preparation and'the bottom roller isprovlded with longitudinal or circumferential grooves wh ch'may be continuous or in short lengths and" parallel or otherwise and straight or curved or with other i'ndentations in accordance with the way in which t is desired to apply the ridges and (or) spots of adhesive to the surface of the fabric, said grooves or indentationshavin a suitable space between them, the other ro ler I being madewith a covering of rubber or the like so that it has a more or lessyieldingsurface and the latter roller, during opera-J tion ofthe machine, is maintained wlth a downward pressure by any suitable means and 1n connection with the bottomroller I preferably provide a gage knife or equivalent to control the amount of the adhesive preparation on the surface of the cylinder as it passes toward the nip of the rollers where the adhesive preparation is taken up by the cloth or fabric, this bein effected b the passing of the cloth or fabric through between the rollers where the yielding pressure of the top roller on the fabric causes the latter to dip into the grooves or'indentations in the surface of the bottom roller and so. lift the adhesive substance out of same on to the undersurface of the fabric.

When the surface of the roller has passed through.

In order that my invention may be clearly understood I have hereunto appended an explanatory sheet of drawings whereon I have shown by Way of illustration or ex ample a machine adapted for applying a semisolid adhesive to fabrics, in'accordance with my invention.

Figure 1 is a part sectional side elevation of the machine. Fig. 2 is a plan view thereof and Fig. 3 a part front sectional elevation on the line :1; m, Fig. 1. Fig.4 is

an enlarged view of a portion of a grooved rolleri-"andalso showing: how'ithefabric is pressed into the suitable adjustable bearing surfaceof the u per roller. Fi 5 shows sdziie-difierent forms ofbottom ro lersshowing continuous gr0oves,short length grooves, curved grooves, and spot indentations.

The .machineshown at Figs. 1 to 3 comprises a frame a su porting a tank 6 and to and bottom rol ers o and d. The to ,roller 0 is. inthis case covered with thic frubberlc and it is adjustably supported in 0 provided in the frame a. "The roller d Is adj ustably supported on the frame a in suitable adjustable ,e

arings d and the roller 0 is adapted to "be pressed downward by the action of the levers e' and weights 6 or springs or equivalent while adjustment of the roller 0 with reference to the roller d is also provided .by'the screw adjustment gear f adapted to raise and lower the bearings of the roller 0. .At the back of the roller 03 a knife g isT-adjustably supported in holders 9 and 1f es1red, a-pointer 9 may be provided on the-holders'g and a scale provided on the part g of the knife'so that fine adjustments ofthe latter relatively'to the surface of the roller d. may be readily made, and only the requisite amount of adhesive substance allowed to remain on the roller d as it passes to the nip a between the rollers c and d.

Asthe roller 03 must be cleaned each time before taking up a fresh supply of the adhesive h from the tank 6, a cleaning brush or comb i is provided and adjustably su ported in holders 2? so that it cleans out t e gfooves or indentations in the surface of t e roller d at each revolution and before the roller takes up a fresh supply of the adhesive preparation.

; ,fllhe adhesive preparation may be filled .into the tank I) in any convenient manner and in order to insure that the roller (I will take up the required amount at each revolutionl may provide a bar or shovel k in any suitable manner, a gear wheel 0 mounted on the axle of the lower roller 12 and enga a second gear wheel 12, rotatably mounted 1n the tank which, inturn, engages a third gear wheel 9 mounted on the axle of a disk crank r rotatably mounted in the side grooves by the yielding.

' mentione vadjustably disposed and havm .which fit into and remove ad at "Fig. 5.show some of the variations of grooves and (or) other indentations which may be provided in the surface of the roller d to roduce different formations of ridges and oi) spots of adhesive substance on a abric m passed between the rollers a and d, and at Fig. 4 the action of the roller 0 with its yielding surface is shown clearly, the

pressureof the roller 0 causing the fabric m to lick up the adhesive substance it out of the grooves d After passing through between the rollers c and d the fabric m with the adhesive preparation on its underside is preferably-passed to a drying cylinder of known construction.

Having now fully described my invention what I c aim and desire to secure by Letters Patent is In apparatus for applying a semi-solid adhesive preparation to the surface of a fabric the combination of an indented roller provided with heating means and adjustably and revolubly su ported in a receptacle for containing the a hesive preparation so that as its periphery passes therethrough the indentations will take-up a supply of the adhesive material, a second roller having a yieldin surface superposed on the first rollerand provided with means whereby its ressure on the under roller can be regulated a knife adjustably disposed relatively to the first mentioned roller to remove adhesive material from its surface as it rises toward the upper roller, a comb projections esive material from the indentations in the first mentioned roller as its surface passes downward .into the receptacle, and an automatically actin shovel for forcing the adhesive materia toward the portion of the roller in the receptacle.

In testimony whereof I afiix my signature in presence. of two witnesses.
